The Tyrant CNC MKII magazine extension for the Glock 17, 19X, 22, 34, 35 and 45 (brand part no. TDG17MAGEXG) adds capacity to 17-round Glock magazines and installs without tools. Tyrant CNC machines each base pad from aerospace-grade aluminum, which adds the weight that helps magazines drop free quickly, and uses a retention plunger so it slides onto the magazine in seconds. The knurled surface gives a secure grip for fast, reliable reloads. Every purchase includes a new power spring, so the longer magazine runs reliably.
